Sennheiser HP 02-140 On-ear headphones with adjustable headband - 55 in. cable, 90° plug (Box of 20) - 505966

Product Overview

The Sennheiser HP 02-140 is a robust, on-ear headphone with an adjustable headband, purpose-built for assistive listening distribution in venues using Sennheiser infrared (IR) and RF hearing assistance systems. Featuring a 55-inch (140 cm) cable terminated with a 90° angled 3.5 mm stereo plug, the HP 02-140 is engineered for comfortable, reliable use when connected to a pocket-worn IR receiver. Sold as a box of 20 units (SKU 505966), it delivers the per-unit economy and consistent performance that institutions require when outfitting entire sections of seating for hearing-impaired guests. Rotatable ear cups and tool-free replaceable ear pads further simplify storage, cleaning, and maintenance between events.

Product Description

Unlike the neckband-style NP 02, the HP 02-140 uses a traditional adjustable overhead headband, offering the broad fit range and familiar wearing position preferred by many audience members. The headband is lightweight and adjustable to accommodate a wide range of head sizes comfortably, making the HP 02-140 suitable for public venues where one-size-fits-all distribution is essential.

Audio performance is specifically optimized for speech intelligibility rather than music reproduction, ensuring that spoken word — whether sermon, public address, theatrical dialogue, or council proceeding — is conveyed with maximum clarity to the listener. The headphones are designed to work with the full range of Sennheiser IR assistive listening receivers, including the SI 1015 and SR 2020 series, as well as compatible third-party IR and RF personal amplifier systems using a standard 3.5 mm stereo output.

The 90° angled plug reduces cable strain at the receiver jack, extending the service life of both the headphone and the receiver in high-rotation venue environments. Rotatable ear cups allow the headphones to fold flat, saving storage space when 20 or more units are stacked in a venue closet or distribution cart between uses. The easily changeable ear pads support hygiene best practices by enabling quick swaps between users without tools, a critical feature for venues that share headphones across multiple services, sessions, or performances.

Frequently Asked Questions

Q: What is the difference between the HP 02-140 and the NP 02?

The HP 02-140 uses a traditional adjustable overhead headband, while the NP 02 uses a neckband that wraps behind the neck. The HP 02-140 is better suited for audiences comfortable with a standard headphone-style fit, while the NP 02 is preferred where users may be wearing hats, religious headgear, or hearing aids that conflict with a top-mounted headband.

Q: Why does the HP 02-140 have a 90° angled plug?

The right-angle plug reduces mechanical stress on the headphone jack of a pocket-worn IR or RF receiver. This extends the service life of both the headphone cable and the receiver’s audio port in high-rotation shared-use environments.

Q: Is the HP 02-140 suitable for music listening?
